In this study, the authors highlight the differences in classroom-, teacher-, and school-level factors in 8th and 9th grade algebra experiences along socioeconomic and racial/ethnic lines using nationally representative survey data from the American Mathematics Educator Study. Several takeaways emerge from this analysis. The analysis shows that…

The current project, Exploring Math Education Relations by Analyzing Large Data Sets (EMERALDS) II, is an attempt to identify specific Common Core State Standards procedural, conceptual, and problem-solving competencies in earlier grades that best predict success in algebraic areas in later grades. The data for this study include two cohorts of…

The Rural Math Innovation Network (RMIN) is a 4-year project that launched in January 2017 after receiving a $2.9 million Investing in Innovation (i3) development grant from the U.S. Department of Education (ED) and matching funds from the private sector. Virginia Ed Strategies and rural local education agencies (LEAs) in Virginia are implementing…

The 2021 edition of the Annual Condition of Education Report (COE) marks the 32nd edition of the report. For over 30 years, the Department has published the COE in order to provide education stakeholders critical data about the status of Iowa's education system. The 2021 COE covers a wide variety of content including information about Iowa's…

For over 30 years, the Department has published the Annual Condition of Education (COE) report in order to provide education stakeholders quality information about the status of Iowa's education system. The 2020 COE covers a wide variety of content from information about Iowa's students, schools, educators, administrators, performance and school…

Data and information are critical tools of school improvement. They are the foundation for making informed education decisions for our schools, districts and the state. The 2019 edition of the Annual Condition of Education Report (COE) marks the 30th edition of the Iowa Department of Education report. Much has changed in the past 30 years since…

Data and information are important components of school improvement. They show how schools are changing and how students are progressing. Providing and interpreting data is one of the critical functions of the Iowa Department of Education. The annual Condition of Education report provides valuable data about students, educators and school…

Commencing in 2011, the Mathematics Academies Initiative is a series of professional development academies (lasting 1 to 2 years, depending on cohort) with the primary objectives of (a) providing educators with a high quality professional development experience that enhances their mathematical content knowledge and pedagogical skills, and (b)…

This is the final external evaluation report prepared by SRI International for the Rural Math Excel Partnership (RMEP) project, an investing in innovation (i3) development project funded by the U.S. Department of Education. Operated by Virginia Advanced Study Strategies, Inc. (VASS), the RMEP project included six rural school districts (LEAs) in…

This First Look presents findings from the base-year survey of the newly launched High School Longitudinal Study of 2009 (HSLS:09), the first round of a study that will follow a ninth-grade cohort through high school and into their postsecondary years. HSLS:09 is the fifth in a series of National Center for Education Statistics (NCES) high school…

To ensure that all high school graduates are prepared for the opportunities and challenges that await them, states have increasingly been focused on aligning their end-of-high school expectations with the demands of the real world. In 2005, no state had aligned their expectations with real world demands; now 29 states have adopted college- and…

Eigenvalue is an important concept in Linear Algebra. It is well known that the eigenvectors corresponding to different eigenvalues of a square matrix are linear independent. In most of the existing textbooks, this result is proven using mathematical induction. In this note, a new proof using Vandermonde determinant is given. It is shown that this…

An easy way to present the uniqueness of the square root of a positive semidefinite matrix is given.

Many colleges and universities use a mathematics placement process to guide students to the appropriate entry-level mathematics course. The mathematics placement process presented here was developed over a four year period to make placement recommendations to Calculus I, Precalculus, and College Algebra. Placement recommendations are based on the…
